KIDGARD Seat Belt Guard is currently the only fully adjustable, patented seat belt guard which fits most types of seat belts, preventing young children from opening a seat belt buckle. It offers the unique feature of adhering to the bottom of the seat belt buckle using high quality foam tape selected for its' outstanding high and low temperature adhesive properties. KIDGARD Seat Belt Guard has the patented "Squeeze Sides and Pull" opening feature, which can be easily released by an adult or older child, but not by a child with small hands or a cognitively impaired adult. The recommended use is to secure a child safety seat to the vehicle. This product has been successfully used to keep the occupant in their lap belts, but we don't recommend that use. Please see our video at www.kidgard.net. Recommended age group: 5 years and less.
